What does the red TSI on Volkswagen Tiguan mean?
1 Answers
TSI stands for Twincharged Stratified Injection technology. Here is a detailed explanation of its meaning: T refers to Turbocharging, S refers to Supercharging, and I refers to direct fuel Injection technology. TSI means Twincharged Stratified Injection technology. Additionally, the red SI indicates that the vehicle is a 1.8T model. For the 1.4TSI, the letter I is red; for the 1.8TSI, the letters SI are red; and for the 2.0TSI, all three letters are red. 'Twin Scroll' simply means that through some modifications to the engine's intake tract, it creates two different airflow velocities under high and low loads, better extracting power and reducing turbo lag.
